What controls the part throttle and full throttle timing of the 2-3 upshift on my 87 GN? If I want to increase ONLY the 2-3 shift point by 1-2 hundred rpm or so, is it possible? All my shift points are spaced normal and appropriate except 2-3 which currently happens right after the 1-2 shift. Tightening the TV cable beyond the standard WOT adjustment process we all know how to do only increases all the shift points to too high an RPM and just about knocks the dash onto your lap on part throttle upshifts. For some reason something I did when I installed my trans kit f'd up only the 2-3 upshift and every other tranny function is perfect.
